How it works: When Screentendo launches, you're presented with a box that can be scaled and placed over your browser window. When the box is in place (in this case, over the Google homepage), clicking on the window will make Screentendo create a game map based on what's onscreen. Here, Google's letters turn into the smashable boxes in Mario's world.

What's even cooler: Randall posted the code for free, so it can be edited and modified.

The game itself is pretty simple, and there isn't much to it besides jumping around and smashing boxes. But it could be applied to just about anything. A boring bar graph for work can become an unsolvable quest to save Princess Peach.

And if your job involves building bar graphs, you probably need Screentendo more than anyone.
